Air Barrier paper

A continuous membrane under the cladding of a building. It is often made of a white polyolefin sheet material which is permeable to water vapor but not liquid water or air. This is installed to prevent air and water Infiltration. Acting as an Air barrier it is intended to reduce the air change per hour which results in heat loss or gain, thus lowering energy consumption.

All of these vents are used in some way to remove heat from the attic.

A Soffit vent. Used to allow cooler air from a lower elevation to enter the attic envelope as the hot air escapes the vents above.B Ridge Vent A continuous vent located at the highest peak of the roof to allow uniform ventilation.C Gable Vent These are located high in the end walls at opposite sides of the roof and are used to encourage cross ventilation. D Roof Turbine located near the highest point on a roof. This a vent assisted by the wind or a motor.
